Odin (satellite)

The main instrument on Odin is a radiometer using a 1.1 m telescope, designed to be used for both the astronomy and aeronomy missions. The radiometer works at 486–580 GHz and at 119 GHz. The second instrument on board is the OSIRIS (Optical Spectrograph and InfraRed Imager System). Odin was developed by the Space Systems Division of Swedish Space Corporation (now SSC Sweden) as part of an international project involving the space agencies of Sweden (SNSB), Finland (TEKES), Canada (CSA) and France (CNES). Odin was launched on a START-1 rocket on 20 February 2001 from Svobodny, Russia. The operator announced in 2025 that the satellite is expected to burn up in the atmosphere in the second quarter of 2026 and is expected to be operational until then, outliving the expected two year lifetime by 23 years. ==Lists==
